... of the thermodynamic effect on the mechanism of flashing flow, resulting in a considerable decrease in the flow temperature and the saturated vapor pressure. The flashing nonequilibrium is significantly decreased, forcing the flashing flow to be classified as the usual cavitation behavior and better suited...

... coefficient is in better agreement with experimental data for high-temperature water compared to the existing numerical data. Although the temperature depression inside the cavity is confirmed numerically, the thermodynamic effect shows a weak impact on the cavitation behavior near the boiling temperature...

... dynamics, which involves the use of a homogeneous model coupled with a thermal transport equation, is a powerful tool for the prediction of cavitation under thermodynamic effects. In this study, a thermodynamic model for a homogeneous model is introduced. In this model, the source term related...

...Yoshiki Yoshida; Hideaki Nanri; Kengo Kikuta; Yusuke Kazami; Yuka Iga; Toshiaki Ikohagi The relationship between the thermodynamic effect and subsynchronous rotating cavitation was investigated with a focus on cavity fluctuations. Experiments on a three-bladed inducer were conducted with liquid...

...Yoshiki Yoshida; Yoshifumi Sasao; Mitsuo Watanabe; Tomoyuki Hashimoto; Yuka Iga; Toshiaki Ikohagi Cavitation in cryogenic fluids has a thermodynamic effect because of the thermal imbalance around the cavity. It improves cavitation performances in turbomachines due to the delay of cavity growth...

... of the tip cavity length in liquid nitrogen ( 76 K and 80 K ) as working fluid with that in cold water ( 296 K ) allowed us to estimate the strength of the thermodynamic effect on the cavitations. The degree of thermodynamic effect was found to increase with an increase of the cavity length, particularly...

...Satoshi Watanabe; Tatsuya Hidaka; Hironori Horiguchi; Akinori Furukawa; Yoshinobu Tsujimoto The suction performance of turbopumps in cryogenic fluids is basically much better than that in cold water because of the thermodynamic effect of cavitation. However, it is not still clear how...

...Satoshi Watanabe; Tatsuya Hidaka; Hironori Horiguchi; Akinori Furukawa; Yoshinobu Tsujimoto It is well known that the suction performance of turbopumps in cryogenic fluids is much better than that in cold water because of the thermodynamic effect of cavitation. In the present study, an analytical...
